摘要
从辽宁省西北地区根系土壤中分离得到DW22号内生真菌,液体培养后,分别用20%、40%、60%、80%、100%乙醇提取其次级代谢产物,依次编号为22-1、22-2、22-3、22-4、22-5。进行抗稻瘟病菌的抑制活性检测和方差及差异显著性分析。结果表明:20%乙醇提取DW22号内生真菌次级代谢产物对抑制稻瘟病菌有较好的效果。
Secondary metabolites from DW22, an endophytic fungus isolated from root-zone soil col- lected in Northwest of Liaoning, were extracted with 20%, 40%, 60%, 80% and 100% ethanol, respectively. The ethanol extracts were numbered with 22-1, 22-2, 22-3, 22-4 and 22-5 in order. Inhibitory activities to Magnaporthe grisea were detected, and the variances and significant differences were analyzed. The results showed that 20% ethanol extract of secondary metabolites from DW22 endophytic fungus had better inhibit- ing effect to Magnaporthe grisea.
